环境准备：

https://download.redis.io/releases/

redis 部署

三台分别执行，除ip、端口不一致

mkdir /data/redis -p
cd /data/redis
wget https://download.redis.io/releases/redis-5.0.9.tar.gz
tar xf redis-5.0.9.tar.gz
cd redis-5.0.9
yum install gcc -y 
make && make install
mkdir {7001,7002}/{conf,db,log} -p

编辑配置文件 注意修改bind，改为服务器ip

#7001
cd /data/redis/7001/conf
vim redis_7001.conf 
daemonize yes
bind 192.168.0.57
port 7001
pidfile /data/redis/7001/redis_7001.pid
logfile /data/redis/7001/log/redis_7001.log
dbfilename "redis_7001.rdb"
dir /data/redis/7001/db/
requirepass Mogu07550831
appendonly yes
appendfilename "redis.aof"
appendfsync everysec
cluster-enabled yes 
cluster-config-file nodes_7001.conf
cluster-node-timeout 15000
masterauth Mogu07550831

#7002
cd /data/redis/7002/conf
vim redis_7002.conf 
daemonize yes
bind 192.168.0.57
port 7002
pidfile /data/redis/7002/redis_7002.pid
logfile /data/redis/7002/log/redis_7002.log
dbfilename "redis_7002.rdb"
dir /data/redis/7002/db/
requirepass Mogu07550831
appendonly yes
appendfilename "redis.aof"
appendfsync everysec
cluster-enabled yes 
cluster-config-file nodes_7002.conf
cluster-node-timeout 15000
masterauth Mogu07550831

注：将这两个配置文件 分发到192.168.0.58、59服务器上，文件地址保持一致，更改ip地址

启动 三台都执行

/data/redis/redis/src/redis-server /data/redis/7001/conf/redis_7001.conf
/data/redis/redis/src/redis-server /data/redis/7002/conf/redis_7002.conf

初始化集群,在7001上操作

redis-cli -a xingdaokeji.0 --cluster create 192.168.0.57:7001 192.168.0.58:7001 192.168.0.59:7001 192.168.0.57:7002 192.168.0.58:7002 192.168.0.59:7002 --cluster-replicas 1

确认集群配置信息，输入yes后开始分配槽位
